Just recently got my ktuner v2, super excited

Did my first 2 datalogs tonight just driving around and not really pushing it at all above 3k RPM & half throttle. When I was looking into my datalogs in the ktuner exe I saw cylinder misfire on 1,3,4 and cyl knock on 1 & 4 sometimes. I know this might have something to do with having a CAI & exhaust but how do I fix this?

Sorry if this is a stupid question, I'm extremely new to this whole thing.

Have it tuned for your intake, as improperly designed intakes will throw fueling off.

Thanks! Would this be something I could do on my own with some help, or would I be better off paying someone to do it for me?

There's plenty of information out there regarding tuning both MAF and Speed Density. You have both options in the software, so that's sort of up to you. If you don't feel comfortable find a professional.
